625 bool "kexec system call (EXPERIMENTAL)"
626 depends on SUPERH32 && EXPERIMENTAL && MMU
628 kexec is a system call that implements the ability to shutdown your
629 current kernel, and to start another kernel. It is like a reboot
630 but it is independent of the system firmware. And like a reboot
631 you can start any kernel with it, not just Linux.
633 The name comes from the similarity to the exec system call.
635 It is an ongoing process to be certain the hardware in a machine
636 is properly shutdown, so do not be surprised if this code does not
637 initially work for you. It may help to enable device hotplugging
638 support. As of this writing the exact hardware interface is
639 strongly in flux, so no good recommendation can be made.
642 bool "kernel crash dumps (EXPERIMENTAL)"
643 depends on SUPERH32 && EXPERIMENTAL && BROKEN_ON_SMP
645 Generate crash dump after being started by kexec.
646 This should be normally only set in special crash dump kernels
647 which are loaded in the main kernel with kexec-tools into
648 a specially reserved region and then later executed after
649 a crash by kdump/kexec. The crash dump kernel must be compiled
650 to a memory address not used by the main kernel using
653 For more details see Documentation/kdump/kdump.txt

659 Jump between original kernel and kexeced kernel and invoke
662 config PHYSICAL_START
663 hex "Physical address where the kernel is loaded" if (EXPERT || CRASH_DUMP)
666 This gives the physical address where the kernel is loaded
667 and is ordinarily the same as MEMORY_START.
669 Different values are primarily used in the case of kexec on panic
670 where the fail safe kernel needs to run at a different address
671 than the panic-ed kernel.
674 bool "Enable seccomp to safely compute untrusted bytecode"
677 This kernel feature is useful for number crunching applications
678 that may need to compute untrusted bytecode during their
679 execution. By using pipes or other transports made available to
680 the process as file descriptors supporting the read/write
681 syscalls, it's possible to isolate those applications in
682 their own address space using seccomp. Once seccomp is
683 enabled via prctl, it cannot be disabled and the task is only
684 allowed to execute a few safe syscalls defined by each seccomp
690 bool "Symmetric multi-processing support"
691 depends on SYS_SUPPORTS_SMP
692 select USE_GENERIC_SMP_HELPERS
694 This enables support for systems with more than one CPU. If you have
695 a system with only one CPU, like most personal computers, say N. If
696 you have a system with more than one CPU, say Y.
698 If you say N here, the kernel will run on single and multiprocessor
699 machines, but will use only one CPU of a multiprocessor machine. If
700 you say Y here, the kernel will run on many, but not all,
701 singleprocessor machines. On a singleprocessor machine, the kernel
702 will run faster if you say N here.
704 People using multiprocessor machines who say Y here should also say
705 Y to "Enhanced Real Time Clock Support", below.
707 See also <file:Documentation/nmi_watchdog.txt> and the SMP-HOWTO
708 available at <http://www.tldp.org/docs.html#howto>.
710 If you don't know what to do here, say N.
713 int "Maximum number of CPUs (2-32)"
716 default "4" if CPU_SUBTYPE_SHX3
719 This allows you to specify the maximum number of CPUs which this
720 kernel will support. The maximum supported value is 32 and the
721 minimum value which makes sense is 2.
723 This is purely to save memory - each supported CPU adds
724 approximately eight kilobytes to the kernel image.
727 bool "Support for hot-pluggable CPUs (EXPERIMENTAL)"
728 depends on SMP && HOTPLUG && EXPERIMENTAL
730 Say Y here to experiment with turning CPUs off and on. CPUs
731 can be controlled through /sys/devices/system/cpu.
733 source "kernel/Kconfig.preempt"
737 depends on !SMP && SUPERH32
739 This enables support for gUSA (general UserSpace Atomicity).
740 This is the default implementation for both UP and non-ll/sc
741 CPUs, and is used by the libc, amongst others.
743 For additional information, design information can be found
744 in <http://lc.linux.or.jp/lc2002/papers/niibe0919p.pdf>.
746 This should only be disabled for special cases where alternate
747 atomicity implementations exist.
750 bool "Implement atomic operations by roll-back (gRB) (EXPERIMENTAL)"
751 depends on GUSA && CPU_SH3 || (CPU_SH4 && !CPU_SH4A)
753 Enabling this option will allow the kernel to implement some
754 atomic operations using a software implementation of load-locked/
755 store-conditional (LLSC). On machines which do not have hardware
756 LLSC, this should be more efficient than the other alternative of
757 disabling interrupts around the atomic sequence.
